PACIFIC 33VM52-000-29 伺服电机模块首要是经过建筑物地下网状接地体系到达要求。变频器体系防雷时还要求对相邻两建筑物之间经过的电力线，信号传输电缆均必须与建筑物接地体系衔接起来(不能形成回路)，以使用多条并行途径来削减电缆中的电流。变频器体系的接地更应当注意体系的安全性和防止其它体系搅扰。一般来说作业状态下变频器体系接地不能直接和防雷地线相连，不然将有杂散电流进入变频器体系引起信号搅扰。正确的衔接方式应当在地下将两个不同地网，经过放电器低压避雷器衔接，使其在雷击状态下主动连通。

33VM52-000-29 is developed based on general configuration software, with easy expansion of functions and convenient addition, modification, and upgrade of functional modules according to user needs. We plan to reserve integrated control data interfaces and bidirectional data transmission modules to provide useful data support for the factory to complete its informatization upgrade. The system can facilitate the connection between scanning equipment and third-party databases, and can facilitate the completion of management requirements such as product quality traceability. From a theoretical perspective, shielding is very useful for lightning protection of the frequency converter casing. However, from an economically reasonable perspective, different shielding methods should still be selected based on the immunity of equipment components and the requirements for shielding effectiveness. Line shielding, which refers to the use of shielded cables in frequency converter systems, has been widely used. But the shielding requirements for equipment or systems depend on the specific situation. The iec proposed an example of using building steel bars to connect to metal frames.

The PACIFIC 33VM52-000-29 servo motor module primarily meets the requirements through the underground network grounding system of the building. When lightning protection is applied to the frequency converter system, it is also required that the power lines and signal transmission cables passing between adjacent buildings must be connected to the building grounding system (without forming a circuit) to use multiple parallel paths to reduce the current in the cables. The grounding of the frequency converter system should pay more attention to the safety of the system and prevent interference from other systems. Generally speaking, the grounding of the frequency converter system cannot be directly connected to the lightning protection grounding wire during operation, otherwise stray current will enter the frequency converter system and cause signal disturbance. The correct connection method should be to connect two different grounding grids underground through the low-voltage lightning arrester of the discharge device, so that they can actively connect under lightning strikes.

PLC内的I/O模板，除一般的DI/DO、AD/DA模板外，还发展了一系列特殊功能的I/O模板，这为PLC用于各行各业打开了出路，如用于条形码识别的ASCII/BASIC模板，用于反馈控制的PID模板，用于运行控制、机械加工的高速计数模板、单轴位置控制模板、双轴位置控制模板、凸轮定位器模板、射频识别接口模板等，这在以后还会有很大发展。另外在输入、输出的相关元件、强干扰场合的输入、输出电隔离、地隔离等方面也会更加完善。
